Patented Oct. 27, 1931 UNITED STATES PATENT OFFICE JOSEPH D. ZUBIA AND MANUEL S. GUTIFIRREZ, LOS ANGELES, CALIFORNIA DETACHABLE SHOE HEEL Application filed June 10,

Our invention relates to detachable shoe heels of the character embodied in our pendin application Serial No. 446,087 filed April 21, 1930, and it is a purpose of our invention to provide in a detachable shoe heel, a heel of a unitary light and hollow structure as distinguished from a built-up heel, and which heel is cast from metal or molded from a suitable composition to produce a heel having the desirable characteristics of lightness, cheapness, and a permanency of form.

It is'also a purpose of our invention to provide detachable shoe heel having means associated with the latch for securing the heel to the shoe, which is operable to aid in removing the heel from the shoe, thus greatly facilitating such removal even under adverse conditions such as when the contacting parts of the heel and shoe have become rusted or covered with mud.

A further purpose of our invention is the provision of a resilient medium interposed between the shoe and the heel which is operable when the heel is attached to the shoe to prevent even the slightest movement of the heel on the shoe in order that the heel may properly function to support the heel end of the shoe and without any wobbling movement.

30 We will describe only one form of detachable shoe heel embodying our invention, and will then of in claims.

In the accompanying drawings:

' Fig. 1 is a fragmentary view showing in vertical longitudinal section, one form of shoe having applied thereto one form of detachable heel embodying our invention.

Fig. 2 is a view similar to Fig. 1 showing 40 the released position of the parts for holding the heel of the shoe incident to removal of the heel. r V Fig. 3 is a vertical transverse sectional view taken on'the line 3-3 of Fig.1.

Fig. 4 is a detail perspective view of the heel detached from the shoe.

Fig. 5 is a detail perspective view of that part of the device which is permanently attached. to the shoe.

As in our pending application, our prespoint out the novel features there- 1930. Serial No. 460,222.

ent invention includes a metal plate 15 adapt- I, u

ed to be permanently secured to the under side of a shoe S, and to which latter is secured a head H. A tongue T is formed on the head,

and is adapted to be received Within a cone spondingly shaped groove G of a heel D, the tongue extending longitudinally of the head and the groove transversely of the heel so that when the heel is applied to the head it will be properly positioned to support the rear end of the shoe.

The head H has a convex surface to fit the concave surface on the upper end of the heel D, but this concave surface is not continuous in the present form of heel by reason of the ,6?

fact that the heel is hollow and cast from suitable metal or molded from a suitable composition of material. Those surfaces which coact to form a surface of concave form are clearly illustrated in Fig. 4. The heel D may and to the lower end of which plug is secured a tip 18 of leather or rubber in order to form the bottom sole for the heel. As best shown in Fig. 4;, the front wall of the heel adjacent the groove G is recessed as indicated at 19 to form a keeper for a latch lever 20 pivoted at 21 in the tongue T and provided with an arm 22 which extends through a slot 23 of a plunger 24, the latter being movable in a suitable opening in the tongue for the purpose of moving the latch 20 into and out of engagement: with the keeper 19. This plunger is normally urged forwardly or outwardly by means of a spring 25 and to a'position in which the lever 20 is projected to engage the keeper 19 for latching the tongue T against removal from the groove G.

The inner end of the plunger carries a lug 26 which is adapted to engage a partition 27 of the heel D only when the plunger is forced inwardly, as illustrated in Fig. 2, and for.

the purpose of aiding and effecting removal of the heel from the shoe. This partition 27 i is formed interiorly of the heel 'D and in spaced relation to one end of the latter to providean intervening pocket 28 in'which a body 29 of resilient material such as rubber is adapted to be received. This body29 is provided with an'extension 30 projecting into'ia V groove 31 of the partition 27 and in such. manner that the extension is locked in the groove tofhold the 'bo-dy'29 against displace ment from thepocket and in proper position therein to eifectively perform the function for which it is intended. This important to- 19 and thussecures the tongue against dis-- placement from the groove. The heel is therefore now locked to the shoe. With the heel appliedas described. the re- ]si'lient body 29 is under compression in order to take up any lateral or transverse play of the heel in respect to the head. 'The extenabuts the extension.

sion 31islikewise under compression by'reason of the fact that the rear-end of the tongue operates in conjunction'with thelatchQO to prevent any longitudinal movement of the tongue in the groove and in amanner'to secure the heel'against movement longitudinally of the head. It will thus beseen that the'heel, when onceappl-ied, is secured against even the slightest wobbling movementupon the head. r v 7 To effect removal of the heel from the shoe, it is only necessary-topress the plunger '24 inwardly against the tension of the spring 25 to move the latch out of engagement with the keeper 19, whenthe .h eel may be removed heel become jammed upon the head by 'rea-V by pushing it rearwardly' to withdraw the tongue T from the groove G; Should the son of rust,.or mud entering betweenthe heel. and head or'betwe'en the tongue and groove, theremova'l of the heel willbe rendered more difiicult, but by provision of the lug 26, re-
